Whether washing vegetables, washing rice or scrubbing greasy dishes and chopsticks, bacteria and dirt in the kitchen sink are also important cleaning items. Therefore, we should attach great importance to the cleaning and maintenance of sinks. 1. After using the sink, be sure to clean it and suck up the residual water with a rag to keep it dry. Similarly, do not leave wet dishwashing sponges or other cleaning pads in the sink. On the one hand, tap water itself contains a small amount of chlorine, and the residual water may lead to mineral deposition. On the other hand, domestic wastewater is also prone to water stains. 2, similar to eating too much sugar can cause tooth decay. Do not leave lemons, sauces, pickles, mustard or other salty or corrosive foods on the sink and panel for a long time to prevent them from corroding the sink. Usually use neutral detergent to clean the sink. 3. Don't use scouring pad, polishing sheet or polishing material to clean the sink for a long time, which will make the surface of the sink rough; If rust and spots appear in the sink, you can apply some toothpaste and scrub with a rag. 4. Try to avoid sharp and hard instruments such as knives, forks and cookers hitting the sink, so as not to scratch or bump the appearance of the sink. Do not cut food or hard objects directly on the sink panel to prevent the sink from deforming and cracks at the joint between the sink edge and the countertop.
